Getting the word about about the product and about you as the guru is most important right now. Write articles for print and for your own website and use "creator of the dvd...." in the tagline. Make sure the article ties to your expertise as the yoga-core expert.

Make your Facebook and Tweets informative rather than sales-oriented, then just include a link to your place of purchase (do you have it set up to buy on your website- then your link) and a "for more information visit...) create friends and followers via Facebook and then get them to re-tweet your information to build a viral spread of your product information.

Host presentations and talks...or volunteer as a guest speaker...be informative and then bring some along for back-of-the-room sales.

Come up with a next product for it...a workbook that goes along with it for proper asana or a nutritional component that will help. Offer one for sale and the other as a "free" bonus.
